Interface Catalysts of Ni/CoN for Hydrogen Electrochemistry.

The development of active, durable, and nonprecious electrocatalysts for hydrogen electrochemistry is highly desirable but challenging. In this work, we design and fabricate a novel interface catalyst of Ni and CoN (Ni/CoN) for hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR). The Ni/CoN interfacial catalysts not only achieve a current density of -10.
